Final answer:
The DSM-5 has been criticized for containing definitions from past decades that are flawed.
Step-by-step explanation:

Some of the definitions and nosologies in the DSM-5 have been carried forward from previous editions, and they may not accurately reflect current understanding or research on mental disorders. This can result in outdated or inaccurate diagnoses and treatments for individuals.
